DETAILED DESCRIPTION OF THE EMBODIMENT

Refer to the FIG. 1 to the FIG. 6. The detailed embodiment of the present invention of a boiler for a steam mop includes a boiler 1, a water inlet pipe 2, a heating element 3, a steam pipe 4 and a steam nozzle 5.

The boiler 1 is cuboid shaped, and four holes are disposed inside along the length direction. Two holes 11 and 13 in the diagonal position are disposed as the liquid way, while another two holes 12 and 14 in another diagonal position are disposed as the way for the heating element 3. The holes 12 and 14 are separately disposed with a crack 121 and 141 on the wall for the material of expanding when heated and contracting when cooled. Two ends of the heating element 3 are separately extended out of the two ends of the boiler 1 and insulated by silica gel cap 9. A cover 8 is disposed in the lower of the boiler 1 to close the two holes 11 and 13. A lateral hole 15 is disposed inside the boiler 1 beside the cover 8 to connect the two holes 11 and 13. The holes 11, 13 and the lateral hole 15 are formed to be a U shaped liquid way. In the end of the boiler 1 not disposed with the cover 8, the openings of the two holes 11 are separately severed as the water inlet and steam outlet.

The water flows to the liquid way of the boiler 1 through the first pipe join 7 from the water inlet pipe 2, then into the hole 13 through the lateral hole 15. The water is heated to be steam by the heating element 3 parallel to the liquid way, and the steam is sprayed out from the steam outlet in the process. As the heating element 3 is parallel to the holes 11 and 13, the water or steam can be heated in the holes 11 and 13 by the heating element 3, making the water completely vaporized inside the boiler without drops of water.

The water inlet of the boiler 1 is connected to the water inlet pipe 2 by the first pipe joint 7, the connection of the first pipe joint 7 and the boiler is thread connection, and the first pipe joint 7 is sleeved and connected to the water inlet pipe 2. The steam outlet of the boiler 1 is connected to a steam pipe 4 through a second pipe joint 6. The connection of the second pipe joint 6 and the steam outlet is threaded connection, and the second pipe joint 6 is sleeved and connected to the steam pipe 4. The other end of the steam pipe 4 is sleeved and connected to a steam nozzle 5.

In this embodiment, the interior diameter of the second pipe joint 6 is 80% of that of the hole 13. The interior diameter of the steam pipe 4 is 90% of that of the hole 13. The interior diameter 51 of the steam nozzle 5 is 80% of that of the hole 13. The nozzle of the steam nozzle 5 is necking down to be a conical nozzle 52 from inside to outside.

As the steam outlet, the pipe joint, the steam pipe and steam nozzle are applied with big inch, it makes sure of steam quantity and prevents blockage of the boiler by calcareous scale. It prevents the boiler from overpressure after cumulating of calcareous scale, the boiler will not be blocked and the mopping effect will not be influenced during usage. Besides, as the head of the steam mop is dismountable, even blockage happens, dismount the head of the steam mop, use a pin to prick the steam nozzle 5 and then wash the nozzle with citric acid or white vinegar to remove the calcareous scale completely and quickly. As the nozzle of the steam nozzle 5 is necking down, the structure is coupled to the big inch outlet, which makes sure of the steam pressure and the strength of the spray steam.

Although the present invention has been described with reference to the preferred embodiment thereof for carrying out the patent for invention, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the patent for invention which is intended to be defined by the appended claims.
